Re: Opening multiple filehandlers

[AgentM]

Be very careful with this! While you may have a legitimate reason for doing this, you can hardly anticipate its failures as cross-platform code. The standard DOS install allowed for 20 file descriptors system-wide! That means that opening 100 would merely crash your program. You would effectively be left with 17 or less file descriptors. On modern OSs, each program may be limited to a certain no. (minimally X by POSIX (Petruchio has my book on this)) and also the system-wide total. It might simply be better to open each file in the loop, output the info, close the filehandle and reuse it.

AgentM Systems nor Nasca Enterprises nor Bone::Easy nor Macperl is responsible for the comments made by AgentM. Remember, you can build any logical system with NOR.

Historically, many unices are set to either 128 or 256. These days I believe Linux is most often at either 256 or 1024 depending on the distribution and sysadmin tinkering. AFAIK the *BSD family tend to 256. I am unaware of PC or Mac defaults and whether they can be changed. IRIX was 256, Sun was 256, HP was 256; last I checked. If you keep it reasonable, say less than 100 you seem to be ok just about everywhere but the pathological cases.
